About a year and half ago, there was a pic of a tangerine patternless posted on the forum here. The breeder was calling them "Tangelos". It was incredibly stunning, the most beautiful gecko I'd ever seen in fact, but I haven't seen one since. However I have seen some orangey-yellow patternless...not enough to be called tang, but not that typical bright yellow-yellow either...
It was actually my admiration of that gecko that influenced the choice of the foundation male for my breeding program, a hypotangerine albino male het for patternless (according to Tremper).
If my male is what R.T. claims he is, and the tremper-patternless genes are compatible, I could be hatching out both tangelos and patternlessless tangerine albinos this year. However I am not holding my breath on that one, given what I have heard from other's about Trempers "patternless" and supposed incompatibility of the patternless and tremper albinos gene sets.
Of course if I do hatch out a patternless tangerine albino this year, everyone on the forum will probably hear my whoops of excitement carry from all the way in S.F. across the country
